Telemedicine

is the use of telecommunication and
information technologies in order to provide clinical
health care at a distance.
It involves secure
transmission of medical data and information,
for the prevention, diagnosis, treatment and
follow
-
up of patients.


Telehealthcare

[From
WiKi
]
is an expansion of
telemedicine,

and unlike telemedicine (which more
narrowly focuses on the curative aspect), it
encompasses
preventative,
promotive

and

curative
aspects
. Originally used to describe administrative or
educational functions related to telemedicine, today
telehealth

stresses a myriad of technology solutions.
For example, physicians use email to communicate
with patients, order drug prescriptions and provide
other health services.

COURSE


This course is called
TeleHealthcare

Engineering
(THE)


That means


we will focus on “engineering”
design of
telehealthcare

technologies. It is unlike
other schools that talk about
telehealthcare

from
“info science” viewpoint. Here we target:



-

Medical sensor hardware;



-

Medical signal processing;



-

Medical signal transmission;



-

Medical security and privacy, etc.

NFRASTRUCTURE

VALUE


Endpoints

and
medical devices
play an
important role in Telemedicine
solution, as they are the ones sending
the requested information (data, voice,
video).



But most of the value is provided by
intelligent call control to video
collaboration
. Voice and video
endpoints, presence, contact center
must be integrated and supported by
call control (using SIP).
The
integration
of video endpoints, directory services
and presence, plus required
QoS

and
security

provides telemedicine
solutions that effect business process
and could not have been offered just
few years ago, without the progress
made towards this integration.
